Comparison of sonic qualities of some tonearms

Since it seems that some on this forum are already on LSD, this quote might help us venture towards the cutting edge of musical and tonearm theory more thoroughly, if that’s even possible:

Forks in the quantum road

At its essence, the ontic vs. epistemic debate hides the ghost of objectivity in science. Onticists deeply dislike the notion that observers could have anything to do with determining the nature of reality. Is an experimenter really determining whether an electron is here or there? One ontic school known as the Many Worlds interpretation would say instead that all possible outcomes are realized when a measurement is performed. It’s just that they are realized in parallel worlds, and we only have direct access to one of them — namely, the one we exist in. In Borgean style, the idea here is that the act of measurement forks reality into a multiplicity of worlds, each realizing a possible experimental outcome. We do not need to speak of the collapse of the wave function since all outcomes are realized at once. 

Unfortunately, these many worlds are not accessible to observers in different worlds. There have been proposals to test the Many Worlds experimentally, but the obstacles are huge, for example requiring the quantum superposition of macroscopic objects in the laboratory. It is also not clear how to assign different probabilities to the different worlds related to the outcomes of the experiment.

The agent and the nature of reality 

On the epistemic side, interpretations are just as varied. The Copenhagen interpretation leads the pack. It states that the wave function is not a thing in this world, but rather a mere tool to describe what is essential, the outcomes of experimental measurements. Views tend to diverge on the meaning of the observer, about the role the mind exerts on the act of measuring and thus on defining the physical properties of the object being observed, and on the dividing line between classical and quantum.

Now consider that, at the time of the Big Bang, the entire cosmos was in a quantum state. When the Big Bang is observed, say with a radio telescope, it is changed by the observer (Copenhagen). What is the nature of this change? One can only supposes that the universe is changed to make the observation itself more likely; that is, to optimize the universe for the being to see furthest back in time, and to ’see’ in the most detail. That being would be the Maximal Observer.

This explains the mechanism behind the Anthropic Principle.

The question is, to what extent should we fund astronomy? Are we in a universal race to see furthest back in time? Mr. President, we cannot allow a Radio Telescope Gap !!!

If you really want to expand your mind further to the cutting edge, consider the possibility that the Big Bang never happened! There’s a rather interesting book by that name: “The Big Bang Never Happened”. I think it’s been decades since I read it, but I might be reading it now…perhaps I never stopped?

Back in the day, ’Big Bang’ was a derogatory name for the theory that eventually came to dislodge ’Steady State’. Perhaps it’s time for the pendulum to swing back.

I used to commute with a Lady, who's husband is a nominee for the Nobel Peace Prize, as a result of their work in astronomy, where the supplied coordinates were located by all the major Institutions known for observing Space.

Curved light was discovered at a particular coordinate, that is now strongly suspected as being the point the Big Bang occurred.

The Theory has moved forward a few steps and the Hypothesis is certainly one that has extended and created a new era of Math.
